I think going to a double action only is a mistake. Most women that I have gone shooting with became very tired of the long trigger pull. I personally think that the model 60 S&W is a great gun for carry and would work for a woman. You may want to have her check out the Ladysmith... It is only 5 shot, but if she needs more then that, then look at a semi-auto 9 in double/single like the XD9 (or other incarnations).
I find that in 38 spc, the recoil on the model 60 is really not bad in standard loads.
